Application filed June 7; 1886. Serial a... 204,307. (No model.)

To all whom it may concern.-

Be itknown that I, SYLVESTER F. HARTLEY, a citizen of the United States,residing at Gouverneur, in the county of St, Lawrence and State of New.York, have invented certain new and useful Improvements inLand-Rollers, of which the'following is ajsp'ecification, referencebeing had therein to theaccompanying drawings. 1

Figure 1 is a front elevation of my improved roller. Fig.2 is an endelevation. Fig. 3 is a partial vertical section on line a; m, Fig. 2,looklng in the direction of the arrow 1. Figs. 4, 4*, and 4" aredetached views showing modifications. Fig. 5 is a vertical section online 1 1 F g. 4, looking in the direction of the arrow 2, Fig. 4. Figs.6and 7 show a modification of one of the bearing-boxes.

The invention'relates to certain novel features ofconstruction andcombination, which will be specifically pointed'out in the claims.

A A are the front and rear sides of the box. B is the tongue. G are endsof the box and are extended down below the body of the box 2 to formhangers for the'roller-sections. These parts A A G G constitute a frame,to which there are attached bearings for the main axle, on which thedrum-sections are mounted, as will be hereinafter explained.

The extreme lower end of each hanger is recessed, so as to straddle andfit closely the three fiat right-angled sides of a bearing, E E. (SeeFigs. 2 and 3.) The hanger is also provided with a narrow throat, 6,extending from the bearing upward, say, half the length of the hanger.The squared or right-angled part of the bearing is provided upon atleast three of its sides with flanges or lips e e, which over lap andengage with opposite sides of the hanger. V

d is a bolt seated in the lower forked end of the hanger below thebearing, and serves to grip or clamp the hanger upon the oppositevertical faces of the bearing. I

As will be readily understood, the throat I) performs the doublefunction of facilitating the desired clamping of the hangerto the boxand of increasing the elasticity of the hanger,

whereby the. bearings can conform to the Y irregular movements of theaxle D without serious cramping of the parts.

F is the seat.

G H H are drum-sections, of which the section G may, when desired, bekeyed to the axle; but I prefer that the outer sections should runloosely on the axle, in order to facilitate turning the rollerin variousdirections, as may be required, without necessitating thateither of theouter sections, H H, should slide. over the ground and to provide auniform motion of seeder on an irregular course.

It will be noticed that the central section,

G, has a length about equal to that of both the j sections of equallength; but Iprefer to make the middle one the longer.

AsshowninFigs.1,2,and3,eachdrum-section has agroove near its ends, whichmaybe conveniently rolled in after the ends of the sheet inner ends areseated in hub L. These spokes are threaded at their outer ends and havenuts, whereby the folly-sections may be thrust out against the innerwall of the shell.

In order to spread the ends of the felly-sections apart, thus producingan additional tension upon the parts, I employ wedges J,

mounted on the outer ends of intermediate spokes, K, with nuts on thespokes to force the wedges between the adjacent ends of the fellies.(See particularly Figs. 2, 4, and 5.)

By an examination of Figs. 1 and 3 it will be seen that although theends of the drum run in close proximity to the hangers G 0, they areprevented from contact therewith by reason of the engagement of the hubsof the drumsection with the inner faces of the axle-bearings, and of thefellies being forced against the inner surface of the shell so tightlythat the ends of the shell, the fellies, and the hubs are maintained insubstantially a uniform relation to the frame -work. Another advantageof using these wedges is this: I am enabled to use fellies of suchlength that when under satisfactory tension their ends are so far apartthat water will readily pass between them, whereby the drum-sections aredrained, it being frequently the case that water, either in the form ofrain or snow, is driven between the spokes to the interior of the drumduring a storm, and would seriously rot the fellies were there nooutlets for it.

In Figs. 4 and 5 the grooving of theshell differs somewhat from thatshown in Figs. 1, 2, and 3, in that it bulges outward, thus forming ribsor beads on the outer surfaces of the drums. This construction hasperhaps some advantages over the other, in that the outer edges of thefellies are seated in grooves instead of straddling ridges, so thatthere is no tendency to split the fellies, but rather a tendency toprevent them from being split. Again, it is probably easier to round theouter edges of the fellies than to groove them; in fact, if the groovesin the shell are wide enough,it may not be necessary to even round theouter edges of the fellies.

In Figs. 6 and 7 I have shown a somewhat different form of bearing,-inwhich the tubular part or cylindrical-shaped part M has anupward-projectin g flange, m, secured to the lower ends of the hangers Gby bolts n n and nuts.

I am aware that in wagon-wheels wedges have been inserted between theends of adjacent fellies and combined with various devices for thrustingthe wedges outward and thereby spreading apart the ends of the fellies;but such devices do not accomplish the same ends in wagon-wheels thatthey do when combined with the other parts which go to make up aland-roller. For instance, one desirable function of these wedges in aland-roller is to keep the ends of the fellies spread apart, and therebyprovide openings for the escape of water from the interior of the drum.Then, again, in a land-roller there is always some kind of a frame in orupon which the central shaft is mounted, with a hanger or a framepieceof some kind close by the ends of the shell at each end-of the machine.Now it is apparent that if there were no means provided for keeping thefellies permanently in their proper relations to the shell, or shells,where more than one are used, there would be great liability of the endof the drum working out beyond the vertical plane of the fellies andinto contact with the adjacent portion of the frame. This objectionableresult is avoided by the use of my invention, which renders it easy forthe operator to keep the fellies forced tightly out against the shell atthe ends of the drum, thus insuring that the shell shall not workendwise relative to the fellies. None of these functions or results isincident to the use of wedges in combination with fellies inwagon-wheels, but are due to the presence of the shell in combinationwith the other parts in a land-roller.

I do not wish to be limited to the exact construction shown of any ofthe parts, because many modifications will suggest themselves to thosewho are familiar with this class of machines without departing from thespirit of my invention.

I do not in this case claim any features except those which arespecifically recited in the claims, reserving the right to claim allother patentable subject-matter in another application which I proposeto file as a division and make concurrent with this one.
